How do I make an actual remote call?
I've followed the guide: https://codelabs.developers.google.com/codelabs/webrtc-web/#4
And gotten their example fully integrated in my application (Angular, TypeScript, multi webcam &etc).
How do I make the remote call actually remote? - I get the idea of a signalling server, but maybe someone can show with basic strings?
I found this, but it's not been updated in a while so I'm not sure what's still valid:
Found some nice sequence diagrams https://webrtc.org/native-code/native-apis/
Setup call

Looking at the MDN documentation IOS/Safari fully supports ServiceWorkerGlobalScope.onfetch but when you look at the FetchEvent specification it says it is not supported at all by Safari.
In particular, I would like to store some state for each client and was hoping to use the fetchEvent.clientId property of the event to index it. Of course I presume I also have access to the fetchEvent.request object otherwise I can't see how a service worker can do anything useful and I could simulate clientID from a passed in parameter in the url. But the docs don't really tell me what IOS/Safari supports and doesn't so I don't know which way to go.
Can someone please tell me precisely what does IOS/Safari pass when it calls the defined onfetch function.
I found the answer to my question by using https://jakearchibald.github.io/isserviceworkerready/demos/fetchevent/
connecting my iPad to my Macbook and debugging my iPad. I was eventually able to open the web inspector for the Service worker for that page, and the console.log showed the event passed in.
FetchEvent.clientID is present but a zero length string. As it happens I did the same thing on my (linux) Desktop using Chrome and its also a zero length string, BUT it has another parameter resultingClientId with what looks like a UUID in it. That parameter is not there in Safari.
The FetchEvent.request is there, and in particular the URL. So I can generate my own client id in the client (I am using Date.now().toString() as that is good enough for my purposes) for use in the service worker. In fact my site without a service worker was using the in the URLs I need to intercept already, so I am happy that I have a solution.
I'm trying to get the Watson Visual Recognition to run client side by using express-browserify with reference to the node-sdk for watson-developer-cloud. The VisualRecognitionV3 makes use of the fs package hence I get the fs.existsSync error when I'm trying to call it from the client-side as the browser doesn't know which filesystem to use. My question is how do I go about creating a so called 'abstraction layer' as I am restricted to using the express-browserify package for cross origin calls.
This thread is pretty helpful in shedding some light but I'm not sure where to start regarding the 'abstraction layer' or if there are any other solutions. Also, would something like socket.io work for this? I've linked a clone of the directory here as it seems less clunky than pasting the multiple portions below.
The repository can be cloned and just requires a personal iam_apikey with relevant launch configuration. Appreciate any pointers. Thanks!
I didn't manage to sort this out with express-browserify due to the require(fs) from browser issue but I was able to get it running using the express-ws package
I am trying to write a small application usingwebrtc that can be used as a messaging/Chat application between 2 computers.
I see this:
http://simpl.info/rtcdatachannel/
and it is not working. any suggestions?
I wrote the simpl.info/rtcdatachannel example. It's only designed to show off data channels working within one page.
For a complete peer-to-peer messaging application, I suggest adding RTCDataChannel functionality to something like apprtc.appspot.com. You could also consider a readymade abstraction library like PeerJS or EasyRTC.
You might also want to take a look at the RTCPeerConnection/RTCDataChannel/signaling codelab I built.
In above example, from the trace log, the ice-candidates are generated, but they are either not exchanged between each other because of there may be problem in sending 'offer' or responding the 'answer'. Also above example works only in chrome( because of only webkitRTCPeerConnection is used, with mozRTCPeerConnection this can work on firefox also.
If you want to develope chat application for only text and not for the video chat, then you can use node-js & socket.io or websockets for this.
You may like :) following two libraries:
DataChannel.js / for webrtc data/text/file sharing (among multi-users)
RTCMultiConnection.js / for data as well as media (screen/audio/video/etc) sharing
Firebase.com is a "suggested" starting point for newcomers; that can be used for signaling. You just need to override "openSignalingChannel" and done!
You should use peer.js (https://github.com/peers/peerjs) or use peer chat (https://github.com/Hironate/PeerChat) if you want to do with node js.
I have an Adobe Air mobile application that has a NetConnection. One on call to my AMF server it makes the call and everything returns fine. When I make a second call my app crashes.
Anyone one run into this?
you're going to need to get more info. Run it in debug mode and you should get a stack trace, variable values and the like.
Figured it out. My models in the client and on the server didn't match. Why AIR just crash and didn't give me an error is weird.
Maybe your server client is the cause of the error!
It may be the reason of automatic combine of the two amf calls by NetConnection.
So, your function on server side will be run twice.
Check your require or require_one on server side.
I'm trying to use the mstscax.dll (Microsoft Remote Desktop Control) to login to a Vista machine that requires Network Level Authentication.
I've played around with all the methods in IMsRdpClientNonScriptable4, IMsRdpClientAdvancedSettings4 and IMsRdpClient6. There are a slew of functions that appear that the might enable this.
EnableCredSspSupport
PromptForCredentials
PromptForCredsOnClient
NegotiateSecurityLayer
Unfortunately the MSDN documentation is pratacily useless and I can find no examples for any of these on the web. I know that it's possible because a product called "Royal TS" can connect this way.
One hint is that both "Royal TS" and Vista's Remote Desktop create a authoriztion prompt that looks like the one from CredUIPromptForWindowsCredentials, this makes me belive that i might be able to use a function like that to get the credential and then possibly use PublisherCertificateChain to tell RDP about it.
Any ideas would be helpful.
So if other people find this:
All that needs to be done is EnableCredSspSupport=true, the problem I had was that I was loading the mstscax.dll manually and the version I was using supported the IMsRdpClientNonScriptable4 interface but simply didn't work. If you just load the control normally just setting EnableCredSspSupport=true works fine.
This property maybe help you
RDPControl.AdvancedSettings8.EnableCredSspSupport = true;
In addition, It also depend on your OS support Network Level Authentication or not.

I've never tried to do what you're doing but I suggest you take a look at the following article:
Multi Remote Desktop Client .NET
The projects uses mstscax.dll.
